Force Push or Pull Contact Force Object Pushes

Force: Push or Pull Contact Force: Object Pushes or Pulls while touching another force Gravity: Force of attraction between 2 different masses Friction: Force that resist motion between two surfaces that are pressed together

Net Force: Overall force Acting on an object when all the forces are combined

Balance: Net Force = O -Same effect if there was no force Unbalance: Can change the motion of an object

ISAAC NEWTON

st 1 Law: An object at rest Stays at rest or an object in motion stays in motion unless acted on by an outside force! Inertia: The resistance of an object to change its motion

nd 2 Law: Force = Mass*Acceleration Standard Unit: Newton (Kg * m/s squared)

The Heavier it is the more force it takes to get it going at the same acceleration

Find the Force If a 5 kg ball is accelerating at 1. 2 m/s², What is his force? 6 Newton A person on a scooter is accelerating 2 m/s². If the person has a mass of 50 kg, how much force is acting on The person? 100 N

Find the Acceleration Half the people on the team decide not to Pull the airplane. The combined force of Those left is 4500 N, while the airplane’s Mass is still 30, 000 kg. What is the acceleration 0. 15 m/s² A girl pulls a wheeled backpack with A force of 3 N. If the backpack has a Mass of 6 Kg, What is the Acceleration 0. 5 m/s²

Find the Mass A model rocket is accelerating at a Rate of 3 m/s² with a force of 1 N, What is the mass? . 3 Kg A boy pushes a shopping cart with a force of 10 N, and the cart Accelerates 1 m/s 2, What is the Mass 10 Kg
